Q value

A charge Q is divided into two charge q and Q-q. The value of q such that the force between them is maximum is

Q.7.The value of

If cosectheta-cottheta=q , then the value of cosectheta is

Q find the value of:- (-4) div (2/3)

Looking at the various electric lines of forces between charges Q_(1) and Q_(2) , find the value of (Q_(1))/(Q_(2))

Looking at the vanous electric lines of forces between charges Q_(1) and Q_(2) find the value of (Q_(1))/(Q_(2))

For the system shown below, the value of Q for which resultant force on q is zero is

If p rarr (p wedge ~ q) is false. Truth value of p & q will be

If 5.21^(p) = 2.86^(q) , what is the value of p/q ?
